Background: If there is a difference in leg length, the center of gravity shifts unilaterally toward the short leg, causing loss of balance and secondary postural imbalance, trunk muscle tone changes, gait abnormalities and pelvic imbalance. Objectives: To investigate effects of self exercise program on leg length, balance in adults with leg-length discrepancy. Design: Single blind randomized controlled trial. Methods: Twenty-eight participants were selected and divided into resistance exercise, flexibility exercise, and core exercise. Each exercise was performed for 40 minutes, 3 times a week for 6 weeks. Leg length and balance before and after exercise were measured and analyzed. Results: Following the interventions, resistance exercise group showed significant improvement in balance, but leg length difference did not show significant results. Flexibility exercise group showed significant improvement in leg length difference, but balance did not show significant results. Core exercise group showed significant improvement in leg length difference and balance. There was no significant difference in the comparison between the three groups. Conclusion: This study suggests that customized exercise according to the patient's level is beneficial to the patients.

탄소 양자점 (CQDs, Carbon Quantum Dots)은 크기에 따라 광 물리적 특성이 다르게 나타나는 소재로 각광을 받고 있지만 용매의 호환성과 화학적 안정성은 개선해야 할 문제로 남아있다. 따라서 CQDs에 여러 소수성 기능기를 도 입하여 고분자 미셀 내부에 들어갈 수 있도록 표면을 개질하였다. 탄소 양자점이 함유된 고분자 미셀의 광 물리적 특성은 흡광, 형광 분광법으로 측정하였다.
